the default IV length thus use the PSA macro PSA_CIPHER_IV_LENGTH
defined to do that.

Use psa_generate_random() to generate IVs instead of
mbedtls_psa_get_random(). mbedtls_psa_get_random() is
meant to be used as the f_rng argument of Mbed TLS
library functions.

Symmetric key management is not intended to be
delegated to drivers. Thus, key management code
for a given symmetric key type should be included
in the library whether or not the support for
cryptographic operations based on that type of
symmetric key may be delegated to drivers.

Isolate the Mbed TLS cipher driver interfaces.
Do the actual cipher operations in utility
functions that are just called by the interface
functions.
The utility functions are intended to be also called
by the cipher test driver interface functions (to be
introduced subsequently) and allow to test the case
where cipher operations are fully accelerated with no
fallback (component test_psa_crypto_config_basic of
all.sh).

As per drivers, pass to the Mbed TLS implementation of

For cipher multi-part operations, dispatch based on
the driver identifier even in the case of the
Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.
This aligns the way hash and cipher multi-part
operations are dispatched.

To run succesfully the test
"PSA sign: invalid algorithm for ECC key" of
test_suite_psa_crypto when ECDSA support is not included
in the library, always return INVALID_ARGUMENT
in case of an ECC key not used for ECDSA, whether
ECDSA support is present or not.
Then apply the same logic to RSA sign RSA and RSA/ECC
verify for the sake of consistency.

For the time being, it is not possible to determine
the size of ECC keys from the arguments of all test

Fix likely harmless undefined behavior in cipher tests pointed out by
UBSan with recent compilers (e.g. Clang 10). When the complete output
is empty, the output buffer is NULL. Adding an integer to a null
pointer is undefined behavior even when the integer is 0, so make a
special case for that.
